Gib-FEEDER.

SPECIFICATION forming part of Letters Patent No. 387,114, dated July 31, 1888.

Application filed October 17, 1887.

T 0 all? whom it may concern:

Be it known that I, NICHOLAS SEIBERT, a citizen of the United States, residing at Malden, in the county of .Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Oil-Feeders, of which the following is a full, clear, and eXactdescription, reference being had to the accompanying drawings, forming part ofthis specification, in which- Figure 1 represents a vertical section through the oil-feeder and steam-regulating valve. Fig. 2 is an enlarged vertical section of the steamregulating valve. Fig. 3 is an enlarged vertical section of the pipes or tubes which form the cooling-spaces. Fig. 4is a perspective view of one end of the steamregulating-valve stem. Fig. 5 is a front elevation of my improved oilfeeder.

My invention relates to that class of oil-feed ers known as displacement-1ubricators, wherein the water of condensation is fed into the oil contained in an oil-feeder, and of its own gravity sinks to the bottom, displacing an equal amount of oil; and my invention consists in the constructions and combinations of devices, which Ishall hereinafter fully describe and claim.

To enable others skilled in the art to make and use my invention, I will now describe its construction and indicate the manner in which the same is carried out.

In the said drawings, 0 represents an oilreservoir of any approved construction, pro vided at its upper end with a filliug-plug, A, and screw-plugs B. At the top the oil-feeder is also provided with a condenser or steamspace, 0, within which steam is condensed. The condenser in the present instance is annular in form, and is designed to make the oil-feeder more compact, and to provide it with a large opening for the lubricant. A checlnvalve, D, in the annular condenser prevents the lubricant being discharged when the steam is shut off; but when the oil-feeder is in operation permits the water of condensation to pass from the condenser through the port U,against the glass S of the sight-feed E, into the feeder.

Within the oil-feeder is a pipe or tube, L, through which the displaced lubricant passes, said pipe having its lower end in communica- Serial No. 252514. (No merlehl tion with a chamber having a port, F, leading to the oil-discharge passage llI.

Freprcseuts a feedvalve for closing the passage F, and G represents a globe-valve placed within the steam-pipe H leading from the boiler and communicating with the steam-passage of the feeder. In addition to these valves I employ another valve, I, having a valve stem, J, projecting through a suitable valveseat, a, and having a projecting end, 0, cut away on one side to permit the passage of a small jet of steam when the valve is released from its seat, as shown in Fig. 2.

P represents the oil and steam pipe leading to the valves and piston of the locomotive, and T indicates the usual waste-water valve.

Referring now particularly to Fig. 1 and to the enlarged section Fig. 3, W is a pipe cast in the oiLfeeder, and through which a second pipe, N, of smaller diameter is passed and made steamtight at both ends. Another pipe, N", of still smaller diameter, having a collar, Y, at its lower end, is screwed into a suitable plug, X, said pipes N and N having holes R at their upper ends, for the purpose of per mitting steam to pass into and fill the annular spaces Q with water. The purpose of this construction is to form a non-conductor of heat to the oil, while it also serves as a cooler to condense steam more rapidly for the condenser G. I prefer for these purposes but one pipe; but if increased condensation is required for the condenser G the shorter pipe may be screwed into plug X. Instead of water, I may fill the spaces Q with other nou conducting material, such as asbestus, cork, or plaster-of-paris; but I prefer water, which is self-supplyiug.

The operation of this device is as follows: As the steam passes through pipe H from the boiler and up through pipes N N to the condenser the heat is transferred to the annular water-spaces Q in the form of globules, which adhereto the sides of the pipes, and as they accumulate pass up and out through the holes R in the pipes N N, and thus prevent the I heat being taken up by thelubricant. Again, the steam passing through a pipe surrounded by water cooler than itself condenses more rapidlythan when it is passed directly into the condenser itself.

The essential objects of my steanrregulating valve I are, first, that it may be opened in a IOO careless manner and still produce a proper result; second, it will only admit a certain amount ofsteam to wash thelubricant upon the valve of the locomotive and yet maintain an even pressure in the oil-feeder, thereby causing a uniform supply of the lubricant, either when the steam is shut off going downgrade or steam on going upgrade; and, third, the valve can be used to shut off the steam when the oil-feeder is to be refilled when the locomotive is running. These features I accomplish by having the stem provided with the projecting end 0 below the seat of the valvestem and made flat, as shown, to permit the passage of a certain volume of steam to carry or wash the lubricant down upon the valves and pistons.

In operating my oil-feeder, fill with oil or tallow at A, open valve G, open valve I a turn, (more or less,) then regulate the amount of lubricant needed. The water of condensation will flow down from the condenser, in and around check-valve D, and through the port or water-passage U, to be observed as it falls against the glass S at the sight-feed E, drop to the bottom,and expel an equal amount of oil, which will pass through oil-outlets L and M, through pipe P, and upon the bearings.

Having thus described my invention,what I claim as new, and desire to secure by Letters Patent, is

1. An oil-feeder having an oil'reservoir, a condenser having a check-valve, and the pipe W, forming an integral part of the reservoir, in combination with a pipe of smaller diameter within the pipe W', thereby forming an annular space between said pipes, said internal pipe having openings near its top whereby it communicates with saidspace, a steampipe leading from the boiler and discharging near the bottom of the internal pipe, and the oil pipe or tube L, said reservoir being provided with the passage M, a valve controlling the communication between said tube and passage, the steam and oil tube V, and aregulating-valve therein contiguous to the oil-reservoir, said valve having its stem, cut away on one side, whereby a uniform volume of steam and lubricant is permitted to flow down upon the valves and pistons of the engine, substantially as and for the purpose described.

2. As an improvement in oil-feeders, the combination of an oil-reservoir, a condensingchamber, a steam-pipe, and an oil-discharge pipe, the combined steam and oil tube V, and the regulating-valve I in the said tube imme diately below the steam-pipe and contiguous to the oil-reservoir, said valve having a projection, 0, below its valve-scat, and having a flattened upper surface, whereby a uniform flow of oil and steam is permitted to the valves and pistons of the locomotive.

3. An oil-feeder having an oil-reservoir, a condenser communicating therewith, and the pipe W, in combination with the steam-pipe II, the pipe N, passing through the pipe \V and having openings in its upper end, and a smaller pipe, N, within the pipe N, having openings at its upper end, said pipes WV, N, and N forming between themselves spaces for containing a nonheat-conducting substance, substantially as described.
